UNDERBODY FOR TAN K-CARS.

Specification of Letters Patent.

Patented June 9, 1914.

Application filed February 13, 1914. Serial No. 818,509.

To all whom it may concern:

Be it known that 1, JOHN FRANKLIN EWELL, a citizen of the United States, and a resident of the city of Chicago, in the county of Cookand State of Illinois, have lnvented certain new and useful Improvements 1n Underbodies for Tank-Cars; and I do hereby'declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates generally to improvements in underbody for tank cars, and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described and then pointed out in the claims.

In the drawings already referred to wh ch serve to illustrate my said invention, Flgure 1 is a plan of my improved underbody for a tank car, the trucks and wheels upon which body is adapted to be mounted not being shown as they are not part of my invention. Said plan discloses only one end of the car body as the other end is of like construction. Fig. 2 is a side elevation of one end of said body showing a fragment of the tank proper in place. Fig. 3 is a vertical transverse section in line 33 ofFig. 2.

Fig. 4 is a front or rear view (both being alike) of the body with the coupler bumper. removed for the sake of more clearly show-.;

ing. the construction. Fig. 5 is a vertical transverse section in line 5-5 of Fig. 2.

It isnow to be noted that I have shown.

no brake wheels, brake levers, links or rods, ladders and other paraphernalia with which tank cars are usua 1y equlpped. These elements are no part of my invention and standard M. C. B. parts may be employed.

Like. parts aredesi ated by corresponding characters or sym of the drawings.

A car body or underframe for tankcarsfor conveying and transporting liquids must possess peculiar qualities 1 to withstand the terrific shocks and reactions incident to the material transported. A car frame of such strength and rigidity as to withstand and absorb the multiplicity of strains while in service, and the reactions created by the flow to and fro of the liquid in t e tanks,

01s in all the figures tween channel 5 and plate 6 there is a short would last only a very short time by reason of the incessant stress and stress reversals causlng fatigue of metal and resultant breaks in the frame.

An underbody capable of the greatest mileage must possess a certain degree of re siliency, so that a slight deflection or deformation may take place in order to a great extent dissipate the strains created.

To better understand my invention, I now refer .to the drawings in which A is a box shaped longitudinal girder-extending from one end to the other of the car frame. This of this girder A, medially of the length thereof, and extending in either direction a suflicient distance to meet the necessary re quirements is a shorter lower cover plate 4, similarly riveted to the lower flanges of the channels 2 and 3.

At a short distance from each end of girder A there is securely riveted a trans verse upstanding channel 5, the. length of which exceeds the width of the box-girder A, so that said channel projects equally beyond said box-girder on either side. Fastened to the upper flange of the said channel 5, of a width equaling the width of the girder is a bent plate 6. Said plate is bent downwardly until the same fits the upper corner. of the girder end, where it is bent downvertically at 8, so as to closecontact with the girder ends. Corner angles 7 fastened to the ends of channels 2 and 3 and suitable rivets 9 are employed to maintain this lower end 8 in fixed position against the girder ends.

Located on the top face of girder A, transversely thereof, and in the space bechannel 10, the flanges 11 and 12 of which are bent their entire length to closely contact with the said channel 5 and plate 6,

. the vertical sling oi the usual design (not shown). itliin the girder and solidly fastened therein a short distance the boiler it are rigidly fastened typical draft bar inech euisi'ns 15 and 1G for connection to the couj ring. The openings 17 and li through ate 8 are for bolts or rivets for toning 1e bumper in place and the opening 18 "or the passage therethrough of car couling shank (not shown).

Attention new directed to the fact that the cross channels 5 at either end of the car frame A are employed as tank stops to prevent longitudinal movement of tank B, as best seen l ig. 9 and will observed that these channels in connection with the bent plate 6 lower extension 8, channel 10, angles 7, and interior on l2 produce structure of extre Where such ri idity is an essential point oi reception of the shock of the If uid in the tank flowing backward and iterard and i pacting against the sank heads l e point Where the tree ve force tted through the CO1" p.

roduce a car U. o or practically set S .neans :lFac-e of which is to meet our oi? the tanlr is to o on that the deepest of the ooivezrure coated directly above l lei 'zudinal ;er line of the girder lor ob as reas. Said block is of considerable less in fixed sition thereon by a plurality of through 2S bearing upon proper Washer straps to prevent indentation. of the Wood. To W the lower :t'ace oi girder directly heneath and in alinenient With channel, there is riveted similar but shorter channel iron 30, an equal overlap of said channel established on either side of the girder and the outer ends are bent upwardly 31 and for the passage therethrough of a car cou "etween the channel 80, 'ctly beneath the girder nixed heavy block having ci cular perpendicular opening 34lfor the reception of the usual round trunnion of a typical truck frame (not shown). Fear the outer ends 31 and 32 are located members 35 and 36 for the purpose of providing side bearings ot the truck just above mentioned.

extending upwardly and inclined inwardly from the upper face of channel 30 near the outer ends thereof to the under es of channeldo are channel iron posts 3']? and 38. At their lower ends they are so cured to channel 30 by angles 39 and 40 and rivets l1, While gusset plates 4-2 and 43 employed to secure proper connection to channel 25. Said gusset plates are of such shape as to receive the upper ends of channel struts 4-1 and 4:5 which extend to the fillets in the lower flanges of the beams 2 and 3 Where the same are fastened in place by angles 16 end rivets 4:7. It will thus be seen that the structure just described serves the double purpose of a saddle for the tank T2 and frame work by which the car body supported upon its trucks, and it is to be understood th t two of these structures, designated as a Whole by the reference letter S in the drawings, are located upon the boxgirder A, a short distance from its ends, which distance varies with the length of the carbodfy and tsnk and the load to be carried.

Located intermediate of and. in spaced relation to structures Ed, 'here are located on girder A plurality o1. nsvcrse channels 50, of the length as kennel. 253, with their outer ends in alineinent. liaid. chan nels are ri eted lit by means of so 51, l. tween the duplicate otained in pee. in upon WttSll n by plates V the outer ends of channel lid to the end while of comparatively light weight,

are amply strong for the purpose intended and possess sutlicient elasticity to prevent fatigue of metal resulting from the incessant shocks received in service. Passing around the tank B a number of hooped rods 59, the ends of "which pass through channels 50, and nuts l: provided to tighten these rod to prevent the displacement of the tank. and F are Wooden runways extending from end to end of the car body and are fastened to the outer ends of the channels 25 and 50, Fig. 1, "While at the ends shorter transverse runways 51 are provided.

While herein I have disclosed the pre ferred method of practising my invention, I desire it understood that I may make such changes and alterations therein as might suggest themselves to the skilled mechanic or permitted under the doctrineof equivalents.

.I-Iaving thus fully disclosed my invention I claim as new and desire to secure to myself by Letters Patent of the United States 1.
